JOHN GEORGE STRUB, OF NEW YORK,'N. Y.

AUTO MTIC GAS-PRES-SU RE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 471,657, dated March 29, 1892.

Application nea Apn 8,1891.

To all whom it may concern:

Be it known that I, JoRN GEORGE STRUB, a resident of the city, county, and State of New 'Yorin have inventeda new and useful Auto`v matic Gas-Pressure Regulator, of which the following is a full, clear, and exact description.l

My invention relates to that class of gaspressure regulators that in themselves automatically regulate the discharge ofthe gas therefrom.

My invention consists in providing beneath an ordinary burner a valve that shall automatically regulate the discharge of the gas, so as to maintain a uniform flame, whether the pressure be great or small.

My invention is illustrated by the accompanying drawings, in which- Figure l is a central section of myimproved burner on an enlarged scale. Fig. 2 is a plan View of the lower portion of my device as it appears when the upper part and also a springcontaining cap are detached therefrom. Fig. 3 is a cross-section on the line 3 3, Fig. l. Fig.V 4 is a crosssection on the linel 4 4, Fig. l and Fig. 5 is a side elevation of the valve.

A is the cylindrically-formed base portion of the burner, threaded at its linner lower end to fit the threaded nippleof a gas-pipe. Itis threaded at its upper end on the outside to receive the burner B.

Within the cylinder A is carried a hollow to allow the flange o. to closely fit and slide Within the same. The upper portion of the base A has a shoulder CZ extending inward,as'

indicated by Fig. l, which allows the upright portion of the plunger to closely fit and slide within the same. Within this shoulder are upright holes e e, that connect the chamber f, formed between the liange aand the shoulder d, with the space within the burner B. A cap E, containing a light spring F, may be fitted over the outside of the shoulder d, so that the spring F will bear on the top of the plunger D, keeping it normally in the position shown in Fig. l. It will nowbe seen that as the gas enters the lower part of the .burner access for the gas.

Serial No. 388,163. (No model.)

vit will first enter the plunger, from whence, by means of the hole b, it will escape into the interior chamber f, thence up through the holes e e into the burner, and then out through the tip of the burner.

In operation as the pressure of the gas from the main increases it will by pressing against the flange aand against the closed upper end of the tubular steing causeV the plunger to rise to a more Aor less extent, which will as it rises cause the hole b in its side to become gradually closed by sliding uppast the shoulder d, thereby regulating to a degree deter mined by the size of the hole b the pressure of the gas which feeds the ame. As the pressure decreases 'the valve will fall, opening the hole b Wider, and thereby giving freer It is obvious that it is notl necessary that the spring-containing cap E be used in my device, as the force of gravity will cause the plunger to operate in the same manner; or if the plunger be not heavy enough itself a slight Weight might be added to the upper part, or, in fact, to any accessible part, to cause said plunger to successfully accommodate itself to the'pressure of the gas.-

Having thus described my invention,what` I claim isi p l. The cylindrical base A, having inner shoulder cl and the vertical perforations e therein, combined with the inner verticallymovable plunger D, having closed top, lower flange a., tubular stem g, and aperture b, and with the burner B, said-flange d litting in the pillar of the burner, so that the gas must pass through the tubular stem g and opening b of the plunger-valve, substantially as shown and described.

2. The combination of the cylindrical base A, having the upright perforations ec therein contained, with the flanged hollow plunger D, havingr closed top and opening b, the cap E, carryingrthe spring F, and the burner B, said plunger tting the pillar of the burner, so that the gas must pass through steln g and opening-b of the plunger, all arranged for the purposesspecied. i
